APM6801-Dx+D

Dolby® Decoders and Encoders

Dolby® encoded signals must be decoded for any audio processing tasks. More and more Dolby® encoded signals are being used in the contribution domain (Dolby® E). Dolby® E encoders and encoders are necessary for these links for voiceover and other audio mixing and processing applications, such as loudness control. On occasion, Dolby® Digital (AC-3) is used for contribution applications, and AC-3 decoding is required for the same reasons. For distribution applications, Dolby® Digital (AC-3) encoders are required.

The APM6801+ Dolby® audio processing modules are part of the 6800+™ modular core processing platform. The modules provide input and output connections on an included breakout cable. Features include right AES unbalanced inputs and outputs, audio metadata over serial RS-232/422, external reference and DARS input and a data I/O for audio tracking video frame synchronizers.

Features

  • Three versions:
    • Dolby® E, Dolby® Digital (AC-3) decoder module
    • Dolby® E encoder module
    • Dolby® Digital (AC-3) encoder module
  • Eight AES I/O with input/output routing and sample rate conversion with bypass
  • Up to 2.5 seconds delay
  • Breakout cable provides discrete AES connectivity
  • For embedded applications, add companion SFS/HMX/HDX modules
  • External reference can be color black or tri-level sync
  • DARS input
